Legal claims defining the scope of protection, as filed with the USPTO.
1. An apparatus for testing brain disorders, the apparatus comprising: a display; a sensor that detects body movement data of a subject; a memory; and a processor that is communicatively coupled to the display, the sensor, and the memory, wherein the processor is configured to: obtain information about the subject, wherein the information about the subject includes at least one of an age, gender and health condition, retrieve initial parameters from the memory based on the information about the subject, wherein the initial parameters include a standard movement accuracy and an initial prompt interval, collect, using the sensor and the display, first body movement data for the subject, wherein the first body movement data is collected based on the initial prompt interval; compute a first body movement accuracy based on the first body movement data, set a second interval based on a comparison of the first body movement accuracy to the standard movement accuracy, collect, using the sensor and the display, second body movement data for the subject, wherein the second body movement data is collected based on the second interval, compute a second body movement accuracy based on the second body movement data, and calculate data indicative of a degree of cognitive impairment of the subject based on the second body movement data and the second body movement data wherein the processor is configured to set the second interval to be: shorter than the initial interval when the first body movement accuracy is greater than the standard movement accuracy, and longer than the initial interval when the first body movement accuracy is not greater than the standard movement accuracy.
2. The apparatus according to claim 1 , wherein the initial parameters further include a degree of adjustment, and the processor is further configured to: form the second interval that is shorter than the initial interval by subtracting the degree of adjustment from the initial interval, and form the second interval that is longer than the initial interval by adding the degree of adjustment to the initial interval.
3. The apparatus according to claim 1 , wherein the body movement accuracy is calculated according to a position accuracy representing a consistent degree of positions computed from the body movement data.
4. An apparatus for testing brain disorders, the apparatus comprising: a display; a sensor that detects body movement data of a subject; a memory that stores initial parameters, wherein the initial parameters include: an initial prompt cycle T o , a maximum prompt cycle T max , a minimum prompt cycle T min , an adjustment degree t, and a standard movement accuracy M o ; a processor that is communicatively coupled to the display, the sensor, and the memory, wherein the processor is configured to: obtain information about the subject, wherein the information about the subject includes at least one of an age, gender and health condition, retrieve particular initial parameters from the memory based on the information about the subject, perform a data collection cycle that gathers body movement data for the subject, wherein the data collection cycle includes: collecting, using the sensor and the display, respective body movement data for the subject, wherein the respective body movement data is collected based on the initial prompt cycle T o in a first instance of the data collection cycle an a calculated interval in subsequent instances of the data collection cycle, computing a respective body movement accuracy based on the respective body movement data collected, and calculating the calculated interval based on a comparison of the respective body movement accuracy to the standard movement accuracy M o , calculate data indicative of a degree of cognitive impairment of the subject based on the body movement data gathered by the data collection cycle wherein on a condition that that the respective body accuracy is equal to or greater than M o , the processor is configured to calculate the calculated interval by, by subtracting the adjustment degree t from the calculated interval to form a new interval, setting the new interval equal to T min , when the new interval is smaller than the minimum prompt cycle T min ; and setting the calculated interval equal to the new interval; wherein on a condition that the respective body accuracy is smaller than the standard movement accuracy M o , the processor is configured to calculate the calculated interval by: adding the adjustment degree t to the calculated interval to form the new interval, setting the new interval to T max when the new interval is equal to or greater than the maximum prompt cycle T max , and setting the calculated interval equal to the new interval.
5. The apparatus according to claim 4 , wherein the data collection cycle further includes calculating a number of times that the data collection cycle has been performed, and not calculating the calculated interval based on the comparison of the respective body movement accuracy after the data collection cycle has been performed a predetermined number of times.
6. The brain disorder evaluation apparatus according to claim 4 , wherein the data collection cycle further includes: determining a new adjustment degree when the new interval is smaller than the minimum prompt cycle T min , wherein the new adjustment degree is determined by decreasing the adjustment degree t by a predetermined range; and determine the new adjustment degree when the new interval is equal to or greater than the maximum prompt cycle T max , wherein the new adjustment degree is determined by decreasing the adjustment degree t by the predetermined range.
7. The apparatus according to claim 6 , wherein, the predetermined range of the adjustment degree is 25% to 50%.
